Real Time Clock/Calendar with EEPROM  
Features  
The ISL12027 device is a low power real time clock with  
timing and crystal compensation, clock/calender, power-fail  
indicator, two periodic or polled alarms, intelligent battery  
backup switching, CPU Supervisor and integrated 512 x 8 bit  
EEPROM, in 16 Byte per page format.  
• Real Time Clock/Calendar  
- Tracks Time in Hours, Minutes, and Seconds  
- Day of the Week, Day, Month, and Year  
• Two Non-Volatile Alarms  
- Settable on the Second, Minute, Hour, Day of the Week,  
Day, or Month  
The oscillator uses an external, low-cost 32.768kHz crystal.  
The real time clock tracks time with separate registers for  
hours, minutes, and seconds. The device has calendar  
registers for date, month, year and day of the week. The  
calendar is accurate through 2099, with automatic leap year  
correction.
